I am attempting to create a ripple like effect on an imageView when it is touched down on, however I do not understand how to implement OpenGL for windows and porting it to iOS. I have attempted to use http://www.codeproject.com/KB/openGL/dsaqua.aspx as well as cocos2d however I find the latter completely and utterly confusing. Would anyone be willing to give some suggestions or can point me in the right direction?
